Embodiment Construction

[0030] refer to figure 1 and figure 2 , in a first embodiment of the invention, a number of silicone-based solar cells 1 are placed on a substrate 2 or a glass carrier forming a solar panel. Below the base plate is a heat transfer element 3 which has a planar surface adjoining the underside of the glass. Here, the outer contour of the substrate and the outer contour of the component are substantially the same to ensure a maximum contact area therebetween for good heat conduction.

[0031] The heat transfer element comprises inlet channels 4, outlet channels 5 and internal passages 6 connecting the inlets and outlets. In this embodiment, the element is made from two sheets of ABS plastic material exhibiting a sufficiently low carbon content and resistance to absorbing moisture to ensure a non-conductive material. The first plate is a flat rectangular plate and the second plate is a rectangular plate provided with a topographical pattern forming the inlet channels 4 , outlet...

Abstract

The invention relates to a heat transfer element and an arrangement using such an element to lower the temperature of solar cells. The heat transfer element is arranged to be placed on the shadow side of and in contact with a panel of solar cells and configured for collecting heat from the solar cells, said element comprising an inlet, an outlet and a internal passage extending between said inlet and said outlet and being arranged to guide a heat transporting fluid. Also the passage is defined between two generally parallel sheets. The arrangement comprises a heat transfer element arranged to be placed on the shadow side of and in contact with the panel and a system feeding a heat transporting fluid to said inlet and receiving the heat transporting fluid from said outlet. The invention also comprises an arrangement for cooling a panel of solar cells, comprising a heat transfer element arranged to be placed on the shadow side of and in contact with the panel and a system feeding a heat transporting fluid to said inlet of the element and receiving the heat transporting fluid from the outlet of said element.

Description

technical field [0001] The invention relates to a heat transfer element arranged to be placed on the shaded side of a solar cell and configured to collect heat from the solar cell, thereby reducing the temperature of the solar cell. [0002] The invention also includes a device for cooling a solar cell comprising a heat transfer element. Background technique [0003] Photovoltaics (PV) is a field of technology that includes solar cells for generating energy by directly converting sunlight into electricity. [0004] Due to the growing demand for solar energy, the manufacture of solar cells has expanded dramatically in recent years. According to some estimates, PV power generation has doubled every two years, with an average annual increase of 48% since 2002. At the end of 2007, according to raw data, the cumulative global power generation was 12,400 MW. Approximately 90% of this electricity generation consists of grid-connected electrical systems. Such devices, which can ...
